Guy Stuart Ritchie (born 1968) is a British film director and screenwriter, also known for his former marriage to {{Music/Madonna}}.

His first film, ''Film/LockStockAndTwoSmokingBarrels'' was a low-budget, humorous crime caper about the [[LondonGangster London underworld]]. It was an indie success and critical darling for its fresh, vibrant style.

He followed up with ''Film/{{Snatch}}'', which was an even bigger success, though some critics complained that he was rehashing his previous film too much. Next, he made ''Film/SweptAway'', a remake of a controversial 1970s Italian film, starring his then-wife Madonna.

''Swept Away'' was savaged by critics, and bombed at the box office. When he returned to familiar territory with the crime caper ''Film/{{Revolver}}'', he tried to mix things up with an EvilPlan and an {{Anvilicious}} {{Aesop}}. The film was so poorly received that it didn't even see wide release in America.

Ritchie then made ''Film/RocknRolla'' in an obvious attempt to recapture the violent and irreverent underworld hijinks of his first two films. It was received better than ''Revolver'', but wasn't really a success. He seemed to be approaching the nadir, but his adaptation of ''Film/{{Sherlock Holmes|2009}}'' appears to have [[CareerResurrection revived his fortunes]]; it received mostly positive reviews, and was successful at the box office, grossing more than all of his previous films combined. The sequel, ''Sherlock Holmes: A Game of Shadows'' was equally successful.

He also produced the TV series ''Series/{{SWAG}}''.
